Filtering nozzle for cigarette

ABSTRACT

A filtering nozzle for cigarette is disclosed. The filtering nozzle comprises a suction type which is an appropriate length of tubular structure having one end being an inlet and the other end being an outlet; a connection tube which is an appropriate length of tubular structure having one end being an inlet and the other end being an outlet; an insertion tubes which is an appropriate length of tubular structure having one end being an inlet and the other end being an outlet; filtering paper being independently covering the outlet of the connection tube and the insertion tube or covering the outlet of the connection tube and the insertion tube.

BACKGROUND OF THE NVENTION

(a) Technical Field of the Invention

The present invention relates to a filtering nozzle device, and inparticular, a filtering nozzle which filters away the nicotine, tarmaterial contained in cigarettes. The filtering nozzle can be repeatedlyuse to effectively control the nicotine and tar amount in the cigarette.

(b) Description of the Prior Art

Nicotine and tar material in cigarette are harmful to smoker. Generally,one end of the cigarette is fitted with a filtering sponge to inhibitnicotine or from being sucked by the smoker. However, the filteringsponge is not effective in prevention the nicotine or tar from enteringinto the smoker while smoking a cigarette.

Conventional cigarette filtering nozzle is shown in FIG. 1. The nozzlecomprises a tubular body and a filtering sponge stuffed at one end ofthe tubular body 1. One end of the tubular body allows the cigarettewith the sponge end to be inserted and the other end of the tubular bodyis an outlet to be placed into the mouth of the smoker such that thenicotine and the tar can be filtered twice. The drawback of thisconventional filtering nozzle is that the component of the filteringnozzle cannot be easily replaced and the amounts of nicotine and tarvary from cigarette to cigarette. Too much filtering of the nicotineor/and tar causes a light to mild taste of the cigarette which may notbe preferred by the smoker. Accordingly, it is an object of the presentinvention to provide a filtering nozzle for cigarette which can overcomethe above drawback.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a filteringnozzle for cigarette comprising a suction type which is an appropriatelength of tubular structure having one end being an inlet and the otherend being an outlet; a connection tube which is an appropriate length oftubular structure having one end being an inlet and the other end beingan outlet; an insertion tubes which is an appropriate length of tubularstructure having one end being an inlet and the other end being anoutlet; filtering paper being independently covering the outlet of theconnection tube and the insertion tube or covering the outlet of theconnection tube and the insertion tube; whereby the outlet of theconnection tube is corresponding to the inlet of the suction tube andthe outlet of the insertion tube is corresponding to the inlet of theconnection tube, forming into a filtering nozzle for cigarette with atleast one layer of filter paper.

Yet still another object of the present invention is to provide afiltering nozzle for cigarette, wherein the filter paper includes facialpaper or paper towel with porosity.

The foregoing object and summary provide only a brief introduction tothe present invention. To fully appreciate these and other objects ofthe present invention as well as the invention itself, all of which willbecome apparent to those skilled in the art, the following detaileddescription of the invention and the claims should be read inconjunction with the accompanying drawings.

DETAILED DESCRIPTON OF THE PREFERRED EMBODIMENTS

The following descriptions are of exemplary embodiments only, and arenot intended to limit the scope, applicability or configuration of theinvention in any way. Rather, the following description provides aconvenient illustration for implementing exemplary embodiments of theinvention. Various changes to the described embodiments may be made inthe function and arrangement of the elements described without departingfrom the scope of the invention as set forth in the appended claims.

Referring to FIGS. 2, 3 and 4, there is shown a filtering nozzle forcigarette comprising a suction tube 10, a connection tube 20, aninsertion tube 30, filtering paper 40.

The suction tube 10 is a tubular body of appropriate length having twoends, the inlet 11, and the outlet 12. The outlet 11 is a flat-shapedstructure which is for the mouth of the smoker.

The connection tube 20 is a tubular body of appropriate length havingtwo ends, the inlet 21 and the outlet 22. The outlet 22 can be connectedto the inlet 11 of the suction tube 10.

The insertion tube 30 is a tubular body of appropriate length having twoends, the inlet 31 and the outlet 32. The inlet 31 is for thepositioning of the cigarette sponge end 51 of a cigarette. The outlet 32can be connected to the inlet 21 of the insertion tube 20.

The filter paper 40 includes facial paper, paper towel or active carbonpaper, and/or paper material with good porosity.

Filter paper 40 is enclosed within the inlets 32, 22 of the connectiontube 20 and the insertion tube 30. Then, the outlet of the connectiontube 12 is mounted to the inlet 11 of the suction tube 10. Next, theoutlet of the insertion tube 30 is mounted to the inlet 21 of theconnection tube 20. Thus, a cigarette filtering nozzle with a layer offiltering paper 40 is thus obtained.

When application, the filtering sponge 51 end of a cigarette 50 isinserted into the inlet 31 of the insertion tube 30. The smoker willsmoke the cigarette 50 via the outlet 12 of the suction tube 10 and thefiltering paper 40 will filter off the excessive nicotine or tarmaterial. Upon application, the suction tube 10, the connection tube 20and the insertion tube 30 can be detached, and the filtering paper 40 isthus replaced.

As shown in FIG. 5, the filtering paper 40 is optionally enclosed at theoutlet 22 of the connection tube 20 or the inlet 21, and as shown inFIG. 4, the filtering paper 40 can be respectively enclosed at theoutlet 22 of the connection tube 20 and the inlet 21, and as shown inFIG. 6, the number of the connection tube 20 can be optionallyincreased, and thus, the filtering paper 40 layer is increased. The morelayers of filtering paper will increase filtering of nicotine or tar.

It will be understood that each of the elements described above, or twoor more together may also find a useful application in other types ofmethods differing from the type described above.

While certain novel features of this invention have been shown anddescribed and are pointed out in the annexed claim, it is not intendedto be limited to the details above, since it will be understood thatvarious omissions, modifications, substitutions and changes in the formsand details of the device illustrated and in its operation can be madeby those skilled in the art without departing in any way from the spiritof the present invention.
